PuLLEY-BLOCK.

SPECIFICATION forming part of Letters Patent No. 268,044, dated November 28, 1882.

Application filed August 4, 1882.

To all whom it may concern:

Be it known that I, WILLIAM ScHoLL, of Marion township, in the county ot' Berks and State of Pennsylvania, have invented certain new and useful Improvements in Pulley-Blocks; and I do hereby declare thatthe following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part ot' this specification, and in which- Figure l is a side elevation of my improved pulley-block, showing a sectional tenoned ring applied to the block. Fig. 2 is an edge view ot' the parts represented by Fig. 1. Fig. 3 shows an open swivel-ring adapted for the pulley-block of Figs. l and 2 when the sectional tenoned ring is removed.. Fig. 4 is a perspective view a swivel-yoke which is interchangeable with the said tenoned ring and swivelring.

This invention relates ,to improvements applicable to pulley-blocks; and the nature of 1n yinvention consists in a pulley-block formed entire, and provided with a sheave and a removable attaching device; also, in a pulleyblock having tlaring openings for the passage of the rope, a niortise adapted to receive a tenon formed on a ring or yoke, eyes to receive ropes or hooks, and a provision for a sheave or pulley 5 also, in a tenoned ring or yoke which is adapted for use in suspending the pulleyblock from a hook, ring, or other object, as will be fully understood from the following description, when Vtaken in connection with the annexed drawings.

The letter A designates the pulley-block, and B the grooved rope pulley or sheave, which latter is applied between the two jaws or cheeks of the block, and is allowed to turn freely about a bolt, C, which passes transversely through the said cheeks and receives a nut, a, on one end.

The ends of the cheeks or jaws of the pulleyblocks are concave vertically, as indicated by and when taken horizontally these ends flare outwardly and upwardly, as indicated by b, Fig. 2. By thus shaping the open ends of the 'block A the rope is freely guided on the (No model.)

pulley, both in entering and leaving the block, and it will be impossible for the rope to kink or to be cut or unduly abraded, for the reason that rounded guiding-surfaces are presented to it on its .way from and to the pulley-block.

The head of the block Ais constructed with eyes E E, which are adapted to receive ropes, hooks, or rings, and between these eyes E E is a mortise cast into the block and designed to receive tenons, as 'will be hereinafter explained. The head of the block A is also constructed with dat and cylindrical bosses, which are in the center ot' the block, and which are perforated laterally to receive the bolt C, that receives the nut a on one end of it, as above described.

Fig. l indicates a pulley-block of the construction above described, and which is provided with a divisible ring, H. This ring is composed of two sections, b b', divided horizontally and vertically. The horizontal division is directly through the ring, and the vertical portion is through the half-tenons c c', which are perforated, as shown, and adapted to receive through the scored portions the bolt C'. This bolt securely holds the said divided ring in place, and by removing it (the bolt) the ring can be coupled to another ring, link, or any other object adapted to receive it.

Instead ot' using the ring H, I inay substitute a hook, H', having a swivel-tenen, c2, applied to it. This hook is provided with lips, through which a screw, t', is applied for readily closing the opening, and it is also provided with a double-beveled stop, d, for checking the lateral vibration ot the block A. The tenon c2 is intended to enter the mortise in the block A, and to be secured thereto by the bolt C.

The Fig. 4 is a yoke having perforations f f vertically through it and eyes n n transversely through its ends.V This yoke, which I now letter J, is adapted to receive ropes for attaching it to a beam or other object, and it is constructed with a swivel-tonon, c2, precisely like the tenon c2 on the hook H.

1t will be seen from the above description that I have a pulley-block formed entire. with eyes to which a tackle can be attached, and with flaringedge jaws which will prevent kinking of the rope, and also with a tenon receiver or mortise to reoeiwa a link, a hook, or a yoke, as I have above described.

Having described my invention, I claim- The combination, with the pu1ley-biock,hav ing a soeketed head, of a split ring having a split tenon and a ooupling-bolt passing transverselyth rough the said pulley-block head and through the tenon, constructed and operating substantially in the manner and for the pur= 1o poses described. In testimony that I claim the foregoing as my own I affix my signature in presence of two Witnesses.
